[See 310 CMR 40.1012 (3)]This AUL is being placed on this property voluntarily to advise current and future property owners and any persons holding an interest in the property of the presence at depths greater than 15 feet below the ground surface of residuals from the former Northampton Gas Light Company’s manufactured gas plant (MGP). The MGP had been located on land to the west of this parcel. This voluntary AUL has been prepared in accordance with the requirements of 310 CMR 40.1074.As of the date of this Activity and Use Limitation Opinion, the property is zoned “Central Business,” which permits commercial and residential use. Background This AUL is being prepared for the Property located along Hampton Avenue in downtown Northampton. The Property subject to this AUL is east of the former Northampton Gas Light Company manufactured gas plant (MGP), which is described further in the following sections. MGP residuals attributable to the release identified by the Massachusetts Department of Environmental Protection (MassDEP) as Release Tracking Number (RTN) 1-14222 have been identified within subsurface soils and groundwater greater than 15 feet below ground surface (ft bgs) beneath the Property The Property on which this AUL is being implemented is currently utilized as an asphalt-paved parking lot, hereinafter referred to as the “Old South Street Parking Lot” (OSSPL). The parcel of land was formerly occupied by the Kimball & Cary Co. coal and wood facility.Three large coal pockets or bins (wood structures used for the storage and transfer of coal) were located in this area adjacent to the New York, New Haven and Hartford Railroad tracks since at least 1884 through the 1950’s.The Mill River was formerly located directly south of the railroad tracks. The river, which flowed from west to east, was diverted in 1940 for flood protection purposes beginning at a point approximately one-half mile west of the former MGP , and its former channel was filled in from that point to the eastern edge of the Old South Street Parking Lot. The former river channel was approximately 30 feet in width. Disposal Site History In 2001, a release of oil and hazardous materials (OHM) was identified at properties to the west of the Subject P roperty.The area to the west of the Subject Property includes the Roundhouse Parking Lot, the Roundhouse Office Building, and the Pulcharski Municipal Building ,which were formerly occupied by the Northampton Gas Light Company’s MGP and the company’s offices.The MGP was initially developed around 1855,coinciding with the construction of the New Haven and Northampton Railroad. Much of the part of the Disposal Site (“the Site”) where the release(s) of OHM occurred was used for the manufacturing, storage,and distribution of coal, water, and oil gas. G as production was discontinued in 1951.Most of the gas manufacturing structures formerly present were demolished in 1962.The property occupied by the MGP and its remaining structures were donated to the City in 1973 . Environmental assessments have been conducted at the Site since 2001 in accordan ce with the requirements of the Massachusetts Contingency Plan (MCP).Bay State Gas Company conducted all of the MCP-required assessment and remediation performed at the Site.The Phase II Comprehensive Site Assessment resulted in a detailed conceptual s ite model for the Site. Some MGP-impacted material, including ash, coal, and clinkers, was likely used as fill material within the footprint of the former facility or was graded and re-worked around the facility.Tar and oily MGP residuals also were likely released from containers or through foundations into the subsurface.The oily MGP residuals, being denser than water,migrated downward through the heterogeneous subsurface fill and glacio-fluvial sand and gravel underlying the facility.Clay and other fine-grained, impermeable soil are present below the sand and gravel at depths ranging from 10 to 35 feet below ground surface. Where the dense oil encountered these fine grained clay or fine -grained soils ,it either accumulated at that location or migrated laterally along the upper surface of the clay/soils.This is the likely mechanism by which the residuals came to be located on the Subject Property.Some MGP constituents have dissolved in groundwater and have migrated advectively with the natural groundwater flow.[Note: The “MCP” is the Commonwealth of Massachusetts’ code of regulations (310 CMR 40.0000) for the notification, assessment and cleanup of disposal sites where a release of Oil or Hazardous Materials has been detected.] Reason for Activity and Use Limitation An AUL is not required by the MCP for this property because MGP residuals attributable to the Site are only located at depths greater than 15 feet bgs beneath the Property as described in detail in the Phase II report. However,to limit future potential exposures to subsurface soil and/or groundwater greater than 15 feet bgs on the Property,certain activity and use restrictions will be placed on the Property. The majority of soils beneath the Property between the ground surface and approximately 10 feet below ground surface (ft bgs) consist of historic fill materials, with a confining clay layer located beneath the fill soils at depths ranging from 20 to 3 5 ft bgs.Since the elevation of the railroad bed was at least as high as the current grade, it is reasonable to infer that the fill materials in the location of the railroad tracks coincide with or pre -date the construction of the railroad.The fill in the river was presumably added around 1940. Average depth to groundwater beneath the Property ranges from 15 ft to 17 ft bgs .As previously discussed, the mechanism of deposition of the MGP materials currently located beneath the urban fill soils either occurred through lateral migration from the MGP along the upper surface of the clay layer or through advective migration with the natural groundwater flow.Soils located between the ground surface and the water table (which consist primarily of historic fill materials) are not included in the disposal site as these soils have not been impacted by the release associated with RTN 1-14222.As such, the water table has been designated as the marker below which certain activities will be required to limit potential exposures to MGP residuals through the implementation of an AUL. Specifically, this AUL will prevent exposures of certain receptors (i.e. children, trespassers,site workers and residents) to MGP residuals in the subsurface beneath the water table.A Method 3 risk characterization was completed to evaluate potential risks associated with the MGP-related compounds in the groundwater and subsurface soil beneath the water table . There are no risks of harm to human health posed by the MGP residuals that are present at the disposal site under current and reasonably foreseeable future activities and uses because h umans are not able to contact the MGP residuals in their present location.Implementation of this AUL will limit future potential exposures to MGP residuals that are present at the Property at depths below the water table elevation.[Note: The MCP allows a risk characterization for a disposal site to be performed by one of three methods: Method 1, which involves a comparison of soil and groundwater contaminant concentration measured at a site to existing numerical standards; Method 2, which involves comparison of soil and groundwater contaminant levels measured at a site to more site-specific numerical standards derived for a particular site; and Method 3, which involves a quantification of total site risk considering on-site receptors, assumed exposure scenarios, and contaminant levels measured at the site.] 1.Permitted Activities and Uses The following activities and uses are permitted at the Property: (i) Excavation and/or removal of potentially MGP-contaminated subsurface soils (below the water table greater than fifteen (15)feet below ground surface)and associated handling and processing (e.g. size reduction, etc.) associated with limited short-term (three months or less) construction work, provided that it is conducted in accordance with the performance standards of the MCP. Such activities must be conducted in accordance with the performance standards set forth by the MCP and conducted under the direction of a Licensed Site Professional (LSP).[Note: An LS P is a person that the Commonwealth of Massachusetts has determined has the appropriate education and experience to manage the assessment and remediation of sites pursuant to the MCP without the direct oversight of the Massachusetts Department of Environmental Protection (MassDEP)].Excavation activities must be conducted in accordance with the Soil Management Procedures pursuant to 310 CMR 40.0030, and/or all applicable worker health and safety practices pursuant to 310 CMR 40.0018; (ii) Activities and uses which are not identified by this Notice as being inconsistent with maintaining a condition of No Significant Risk; and (iii) Such other activities and uses which, in the Opinion of an LSP, shall present no greater risk of harm to health, safety, public welfare, or the environment than the activities and uses set forth in this paragraph. 2.Activities and Uses Inconsistent with the AUL Opinion. Activities and uses which, if implemented at the Property, may result in a significant risk of harm to human health, safety, public welfare, or the environment are as follows: (i)Activities and/or uses which involve the removal and/or disturbance of the MGP- contaminated soil located beneath the water table without prior development of a Soil Management Plan and a Health and Safety Plan in accordance with Obligations (i) and (ii) of Paragraph 3 below;and (ii) Relocation of the MGP-contaminated soil from beneath the water table o n the Property, unless an LSP renders an Opinion which states that such relocation is consistent with maintaining a condition of No Significant Risk. 3.Obligations and Conditions Set Forth in the AUL Opinion. If applicable, obligations and/or conditions to be undertaken and/or maintained at the Property to maintain a condition of No Significant Risk as set forth in this AUL Opinion shall include the following: (i) A Soil Management Plan must be prepared by an LSP and implemented prior to the commencement of any activity that will disturb the MGP-contaminated soil located beneath the water table.The Soil Management Plan must be prepared by an LSP and implemented prior to the commencement of any activity at the Property that involves the disturbance, excavation and/or removal of OHM-impacted soil, with the exceptions described in Paragraph 1 above.The Soil Management Plan should describe appropriate soil excavation, handling, storage, transport, and disposal procedures in accordance with the provisions of the MCP cited at 310 CMR 40.0030 et seq. and appropriate groundwater handling, storage, and disposal procedures in accordance with the provision of the MCP cited at 310 CMR 40.0040 et seq.The Soil Management Plan should include a description of the engineering controls and environmental monitoring procedures, if any, necessary to ensure that workers and receptors in the vicinity are not affected by fugitive dust or particulates from the Property.On-site workers must be informed of the requirements of the Soil Management Plan, and the plan must be available on-site throughout the course of the project; (ii) A Health and Safety Plan pursuant to 310 CMR 40.0018,must be prepared by a certified Industrial Hygienist or other qualified individual sufficiently trained in worker health and safety requirements and implemented prior to the commencement of any activity at the Property which involves the disturbance, excavation and/or removal of OHM-impacted soil, with the exceptions described in Paragraph 1 above.The Health and Safety Plan should specify the type of personal protection (i.e., clothing, respirators), engineering controls, and environmental monitoring (if any) necessary to prevent worker exposures to OHM-impacted soil.Workers must be informed of the requirements of the Health and Safety Plan, and the plan must be available on-site throughout the course of the project;and (iii) Response actions must be conducted in accordance with the Massachusetts Contingency Plan, 310 CMR 40.0000, should an LSP Opinion rendered pursuant to Obligation (i) conclude that future Property u ses and activities, including exposures associated with future building construction, are inconsistent with maintaining a condition of No Significant Risk.
